NVD description

A vulnerability in client join services of Cisco Webex Meetings could allow an unauthenticated, remote attacker to manipulate cached HTTP responses within the meeting join service. This vulnerability is due to improper handling of malicious HTTP requests to the affected service. An attacker could exploit this vulnerability by manipulating stored HTTP responses within the service, also known as HTTP cache poisoning. A successful exploit could allow the attacker to cause the Webex Meetings service to return incorrect HTTP responses to clients.

    Yay, I did a thing for @Oracle knowing they were collaborating with @Akamai and I was applying for a job at Akamai, so I knew it couldn't hurt my chances. 🥰 Same with the Webex CVE-2025-20255 (I forgot about this CVE tbh🤣). TL;DR - I love hacking. 😜 https://t.co/fnLbDXWi1t

    Haha this Axios hack got me thinking... if CVE-2025-20255 (my own) was public, attackers could have used it to send you a REAL Webex meeting link, but it would take you to another attacker controller meeting space using on-demand request smuggling to cache poisoning. 🤣

    Post summary

    The tweet is a speculative comment about a private CVE-2025-20255 and its potential exploitation via request smuggling and cache poisoning, but it lacks concrete evidence, technical detail, or actionable information.
